Switch Alert component to use yaml config file instead of settings.json

Problem/Motivation

✨ Add and configure js-yaml-loader in the webpack.config.josn for the Storyboook Fixed
Alert story settings come from alert.settings.json file, with JSON format.
Now Yaml loader is working and it's better to use YAML format instead of JSON.

Proposed resolution

• Delete alert.settings.json file.
• Add alert.config.yml file and add all config inside it.
